Question

The time that it takes a sound to decrease to _____ of its original level is the reverberation time.

Answer 1

The time that it takes a sound to decrease to 1/1000th of its original level is the reverberation time.

Reverberation time (RT) is that the time needed for the sound in a very area to decay over a selected dynamic vary, typically taken to be sixty decibel, once a supply is suddenly interrupted.

The reverberation time depends chiefly on a room's volume and space and on the absorption at the walls. usually absorption is frequency dependent and so the reverberation time of a space varies with frequency. Some materials that could be used to scale back reverberation are fibre board, serious curtains, plastics etc.
